    Description

      When scheduler preemption is enabled, applications could be preempted if they obtain resource over they should take.
      When a mapreduce application is preempted some resource, it just runs slower. However, when the preempted application is a long-run service, such as tomcat running in slider, the service would fail.
      So we should have a flag for application to indicate the scheduler that those application should not be preempted.
